[2.1.2][Linux] Text Selection is Invisible

[PowerOfVoid]

Selected text is not highlighted (however it is still possible to copy and paste text)

What I did:

• Create a set
• Type some text on a card
• Use the mouse to try to select the text

What I expected:

• The text is highlighted and can be copied/pasted, etc.

What I got:

• The text is not highlighted, but can be copied and pasted, etc.

(I checked while typing this up and discovered that, while there is no visual indication that the text is selected, it can still be copied and pasted or deleted)

Fields where text selection is invisible:

• All tested card fields (text box, artist, name, etc.) ("cards" tab)
• Card notes ("cards" tab)
• Style fields that accept text input ("style" tab)
• Set info fields ("set info" tab)
• Keywords ("keywords" tab)

Fields where text selection is visible:

• Card search ("cards" tab)
• Randomizer Parameters ("random" tab)
• Console ("console" tab)
